The System

The CardioMessenger

Every day, the CardioMessenger automatically collects and transmits data related to your cardiac health and the status of your cardiac device to the BIOTRONIK Home Monitoring Service Center (HMSC) using mobile cellular technology. This data includes:

  • Device function status
  • Battery status
  • The status of pacing or defibrillation therapies delivered
  • Current and historical heart rhythms including any detected abnormalities
  • Overall changes in heart function

The HMSC is a secure, web-based platform where your healthcare team can review your information. Data sent to the HMSC is encrypted to protect your privacy. For more information about the systems used to protect your personal health information, click here.

A Web-Based Monitoring Platform

The transmitted medical and device data is collected, automatically analyzed and filtered by the BIOTRONIK HMSC, according to parameters set by your healthcare team. Health and system-related issues are ranked in order of importance according to the alert status. Important alerts can be sent immediately to a patient’s healthcare team via text message or email. All event and trend reports can be accessed and reviewed through the secure HMSC website.

Setup and Use

Setting up BIOTRONIK Home Monitoring® is simple and, once set up, the system is fully automatic. As a patient, you don’t need to take any further action, other than making sure your CardioMessenger is charged, for successful daily transmissions to your care team. Together with your physician, you can decide what time of the day data transmission will take place. Typically, these transmissions are scheduled to take place while you sleep.

You will receive a CardioMessenger device either at the time of your procedure or shortly after.

On returning home after your procedure, please set up the CardioMessenger as soon as possible, preferably the same day. Setup is easy, with just three simple steps.

Step 1: Remove contents from CardioMessenger box

Step 2: Position the CardioMessenger near your bed (for example, when transmissions are done during the night)

Step 3: Plug the CardioMessenger into a nearby power outlet

After it is plugged in, the CardioMessenger will turn on automatically and perform a self- test. The CardioMessenger is ready to use once the self-test is completed and the following icons are displayed:

If this is not the case, please refer to the CardioMessenger Smart Patient Manual. Both the CardioMessenger Smart Quick Start Guide and the CardioMessenger Smart Patient Manual contain important information concerning the setup and use of your CardioMessenger. Please review each thoroughly.

Your Data and Your Healthcare Professionals

Your healthcare team will review your data at intervals set by the clinic after discussing these options with you. Your physician will generally review reports only during normal working hours. If you have any questions about how your data is being monitored, please ask your physician or care provider. BIOTRONIK Home Monitoring® should only be used as directed by a physician. BIOTRONIK Home Monitoring® may be unavailable due to cellular coverage being unavailable in your area. BIOTRONIK Home Monitoring® may also be periodically unavailable due to cellular service outages in your area or scheduled maintenance. BIOTRONIK Home Monitoring® is not a replacement for emergency care. Please call your regional emergency service.

Why Home Monitoring?

Remote patient management with Home Monitoring offers you the opportunity to benefit from intelligent, event-driven care that improves clinical outcomes without the inconveniences of calendar-based in-clinic follow ups. BIOTRONIK Home Monitoring® can be used to decrease the frequency of in-office follow-ups, which saves you traveling time and expenses.



Improved Patient Outcomes

More than 3,500 patients have been involved in clinical studies of BIOTRONIK Home Monitoring®. These studies demonstrate that Home Monitoring significantly improves clinical outcomes and survival compared with traditional periodic, in-person device follow-up. The IN-TIME study, one of the largest and most recent studies to examine heart failure and remote monitoring, demonstrated a 50% decrease in mortality for patients using BIOTRONIK Home Monitoring®.

Home Monitoring also has been shown to reduce:

  • Hospitalization caused by atrial arrhythmias or strokes by 66% (COMPAS)
  • In-office visits by 45% (TRUST)
  • Inappropriate shock delivery for ICD/CRT patients by 52% (ECOST)

Early Detection

BIOTRONIK Home Monitoring® provides early detection of arrhythmias, including silent, asymptomatic arrhythmias, allowing for earlier intervention (TRUST, COMPAS). Being monitored daily allows earlier detection for:

  • Changes in your heart status that you may not notice yourself
  • Early signs of worsening heart status which could escalate without treatment

The Benefits of Home Monitoring

Historically, patient care guidelines recommended in-person appointments for device patients every three to six months, a time consuming and resource intensive effort for patients and healthcare providers. Moreover, changes in heart status may occur between these appointments. Home Monitoring provides valuable clinical data which could help guide care and possibly prevent hospitalization or even death. BIOTRONIK Home Monitoring® allows follow-up appointments to be catered to you, so that your data is reviewed as necessary, rather than only on a pre-set schedule. You can rest easier knowing that you are being monitored and your healthcare team can be confident that they will be notified of clinically relevant device events in between your in-person visits.
